KovsieSport crowns their best
The University of the Free State honoured their best sports achievers on Wednesday night. The major winners are, from the left: Tyler Beling (best junior sportswoman), Raynard van Tonder (best sportsman),Lynique Beneke (best senior sportswoman), and Rynardt van Rensburg (best senior sportsman).

The athletes Rynardt van Rensburg and Lynique Beneke walked away with the two major awards at the KovsieSport honours function on Wednesday 26 August 2018.

The two were announced as the Kovsie Sportsman and Sportswoman of the Year. Both of them represented South Africa at international level in the past 12 months and were the national student champions in their items.

Van Renburg’s major achievement was the 1:45.15 he ran in the 800 m at the Hengelo World Challenge meeting, which is the 32nd fastest time in the world in 2018 and also his personal best. Beneke, among others, earned a bronze medal at the African Senior Championships in the long jump and won the item at the National track and field championships for a sixth consecutive year.

Tyler Beling, another athlete (middle distance), was named the Junior Sportswoman of the Year while cricketer Raynard van Tonder was the best Junior Sportsman. Van Tonder captained the South African team to the U19 Cricket World Cup, where he scored the third most runs at an average of 69.6. Beling is the country’s best junior in the 1 500 m.

Juanelie Meijer, Louzanne Coetzee (athletics), and Johann van Heerden (swimming) received special awards for their achievements as athletes with a disability.

Other nominees on the night were:

Senior Sportsman of the Year: Ox Nche (rugby).

Senior Sportswoman of the Year: Kesa Molotsane, Ts’epang Sello, Yolandi Stander (all athletics), Khanyisa Chawane, and Meagan Roux (both netball).

Junior Sportsman of the Year: Pakiso Mthembu (athletics), Lubabalo Dobela, and Rewan Kruger (both rugby).

Junior Sportswoman of the Year: Casey-Jean Botha (hockey) and Michaéla Wright (athletics).

Prof Tredoux turns theories regarding the formation of metals on its head
2013-09-17

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.

The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.

This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.

Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.

The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.

For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.

“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”

Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
